My uterus is shedding

Mo
So, first period after getting the IUD, losing my virginity and letting my boyfriend cum in me!! Never been happier to see AF lol 😁 There was a week of brown spotting beforehand which of course since it was earlier than my usual date and had me in a panic about implantation bleeding. But my boyfriend kept reminding me how effective the IUD is. Finally after a couple of days of red blood my uterus is now in full force shedding itself and graciously baby free 😂 I had a period last month too after getting the IUD but never let my boyfriend cum in me then. Feels like these periods last two weeks. It's supposed to calm down after six months right?
